Catharina "Nina" Hagen (born 11 March 1955) is a German actress and singer. Born in the former East Berlin, capital of the German Democratic Republic, Hagen first pursued her career in the mid-1970s. In 1974, she joined the band Automobil. During that time she appeared in a number of German movies. After moving to West Berlin in 1976, she formed the Nina Hagen Band and signed with CBS Records. The band released two albums before Hagen decided to pursue her career as a solo artist.
In 1982, she again signed with CBS Records and released her first solo album, NunSexMonkRock. She later released two more records under the label—the Fearless (produced by Giorgio Moroder in 1983) and Nina Hagen in Ekstasy (1985). Her contract with the label expired in 1986 and was not renewed. She remained popular, making tours and appearances on TV shows. In 1987, the single "Punk Wedding" was released and in 1988, Hagen wrote her autobiography, Ich bin ein Berliner.
Mercury Records offered Hagen a contract in 1989, prompting her to release the eponymous Nina Hagen, an album described as having a more soulful theme than her previous works. She continued to release more albums and tour during the 1990s and 2000s.
Hagen is often referred to as the "Godmother of Punk". She is also noted for her human and animal rights activism.
